Process

Our Process

A practical workflow for Email Deliverability, MTA and Linux, Multi-Cloud, and DevOps assessments, implementation, incidents, validation, and handover.

Four-stage technical investigation moving from evidence intake through diagnosis and controlled repair to validation

Engagement flow

A workflow that turns symptoms into durable fixes.

Intake

Problem brief

Capture the domain, platform, cloud or Linux context, provider signals, recent changes, and production impact.

Evidence

Signal set

Review headers, DNS, logs, bounces, Postmaster, SNDS, queue behavior, and recent incidents.

Triage

Risk map

Separate urgent failures from background warnings so the team knows what matters first.

Root cause

Failure path

Connect the visible symptom to authentication, data, infrastructure, provider, or workflow issues.

Remediation

Fix plan

Prioritize production-safe changes for DNS, sending behavior, Linux, MTA, monitoring, or compliance.

Validation

Check results

Confirm the fix using real signals instead of assuming the problem is gone.

Monitoring

Alert layer

Set up the thresholds, dashboards, logs, and repeat checks needed to catch the next issue earlier.

Handover

Runbook

Leave the team with documented ownership, next actions, and reusable operating guidance.

Signal flow

Each stage has a concrete input, evidence set, and output the team can act on.

Input

Domain, platform, cloud or Linux context, recent change, and the visible failure.

Evidence

DNS, headers, logs, provider signals, queues, dashboards, and recent incidents.

Output

Clear ownership, risk order, remediation notes, and a practical runbook for the team.

Operating model

Eight steps from the visible problem to an operable result.

The evidence changes by service. The discipline does not. Every engagement defines the affected system, proves the cause or requirement, controls the change, checks the live result, and leaves clear ownership.

1. Intake

Capture the affected users, traffic, host, cloud environment, pipeline, service, business impact, urgency, and recent change.

2. Current state

Map the message path, system architecture, cloud topology, deployment flow, dependencies, ownership, and available evidence.

3. Evidence review

Compare the relevant headers, DNS, logs, metrics, provider data, configuration, infrastructure code, deployment history, and operating behavior.

4. Risk and priority

Separate cosmetic warnings from conditions that affect users, delivery, security, stability, resilience, recovery, or operating cost.

5. Change plan

Define the smallest useful sequence, dependencies, owners, validation, security controls, maintenance window, and rollback conditions.

6. Implementation

Apply the agreed DNS, platform, MTA, Linux, cloud, pipeline, container, automation, monitoring, security, or documentation changes.

7. Validation

Check the affected route or environment, compare the result with the baseline, and confirm monitoring can see the expected behavior.

8. Handover

Record findings, decisions, configuration, open risks, thresholds, rollback, recovery, ownership, and the next review point.
